Hoping someone can help me identify this episode/skit. i would have seen the it in 1982-83ish, so it could be older. guy is at a bar trying to pickup chicks... striking out. He sees a guy stuff his pants to make his crotch look bigger. All the girls love the guy now. main character goes in men’s room, finds overalls and stuffs them to the point that his crotch is 6 feet long. next scene is him in the back of a cab with his junk out the window and the car is filled with girls. thats what I remember, but I can never find any skit like that. Maybe SNL maybe not??? thanks for any help!
